Abstract
A heat sink comprises a core member comprising at least one first surface adapted to contact at least a portion of the heat source. An one outer peripheral surface is located on the core member. At least one cooling fin device comprising an inner peripheral surface and at least one cooling fin is adjacent the core member. In one embodiment, the inner peripheral surface of the cooling fin device is adjacent the outer peripheral surface of the core member. At least a portion of the outer peripheral surface is tapered, wherein the circumference of the outer peripheral surface in the proximity of the first surface is greater than the circumference of the outer peripheral surface not in the proximity of the first surface.
Claims31
A heat sink for removing heat from a heat source, said heat sink comprising:
- a core member comprising at least one first surface adapted to contact at least a portion of said heat source;
- at least one outer peripheral surface located on said core member;
- and
- at least one cooling fin device comprising at least one inner peripheral surface and at least one cooling fin associated therewith, said at least one inner peripheral surface of said cooling fin device being adjacent said at least one outer peripheral surface of said core member;
- wherein said at least one cooling fin provides at least one air channel, said at least one air channel being parallel said at least one outer peripheral surface of said core member, and said at least one air channel being adjacent said at least one cooling fin;
- wherein said at least one air channel spirals said core member;
- at least a portion of said at least one outer peripheral surface being tapered, wherein the circumference of said at least one outer peripheral surface in the proximity of said first surface being greater than the circumference of said at least one outer peripheral surface not in the proximity of said first surface.
A method of manufacturing a heat sink, said method comprising:
- providing a core member having at least one outer peripheral surface and a first surface, said first surface being adapted to be located adjacent a heat source, at least a portion of said at least one outer peripheral surface being tapered, wherein the circumference of said at least one outer peripheral surface in the proximity of said first surface is greater than the circumference of said at least one outer peripheral surface not in the proximity of said first surface;
- and
- pressing at least one cooling fin device onto said core member, said at least one cooling fin device comprising at least one cooling device inner peripheral surface and at least one cooling device cooling fin associated therewith.
A method of cooling an object, said method comprising:
- locating a heat sink adjacent at least a portion of said object, said heat sink comprising:
- a core member comprising at least one first surface adapted to be located adjacent said at least a portion of said object;
- at least one outer peripheral surface located on said core member;
- and
- at least one cooling fin device comprising at least one inner peripheral surface and at least one cooling fin associated therewith, said at least one inner peripheral surface of said cooling fin device being adjacent said at least one outer peripheral surface of said core member;
- at least a portion of said at least one outer peripheral surface being tapered, wherein the circumference of said at least one outer peripheral surface in the proximity of said first surface being greater than the circumference of said at least one outer peripheral surface not in the proximity of said first surface;
- a shroud having at least one inner surface, wherein said at least one inner surface is located adjacent said at least one cooling fin device;
- forcing air past said at least one cooling fin device.
